Another object of the invention is toprovide latchmeans or'holiding the sectionsin the top,I ot the car, such means"workinglfautomati'cally to permit vthe sections to'pass on tothetrack parts in thve'top ofthe car and beingraised hand to permit lthe sections tobe loweredtd close the door.

A. fur-ther object of the invention is to make' portions'otthe track 'means j adjustable so thaty theyfcan be' movedabove thel door opening, .when theigrainidor is not in use, so asto' prevent timber and the like, being loaded onthe car, frominjuring suchpo'rf tions. These movable portions also prol vide means' for enabling the door sections to be removed from the track-parts.

This invention also consists `in certain other features of construction and' in. the combinationand arrangement ofthe several parts,' to be' hereinafter fully described, illustratedl in the accompanying drawings and specifically` pointed'tfout in the appended claiIYisl- `Inl describing myy invention in detail," ref erence willf be' had t--lthe accompanying drawings wherein like charac-ters denote like or corresponding parts throughout the several views, and in which Figure ll is atragmentary view of a car showing the gra-inV door in closed position, parts being broken away.

-Figure llis asection online 11e-'l1 of F'gnr'e 6E Y Figure 1 21is a sectionalldetailview show- Figuresl 13- to QOlare sectional detail fviews showingdit'erent forms of trackl parts for thev door sections.

Inf these-views, 1 indicates f a plurality of door-'seetions,` each oit which has asocket Qiformed'in its bottom edge and a reduced part' at its" upp'er'edge, the-reduced part of one 'sect-ionittingin the socket of the other 'section so asf-to: make a grain-tight joint 'betweenthefse'ctions- As shown, I prefer-to bindrthe* edges of` eachl sectionl with metal vstrips '4" to prevent wear, Ithe lower strips formingthe socket 2 and the upper strips coveringthe sides of the reduced' portion. Aheaded projection! 'is located at each end of eaclisection' adjacent the'uplper edge ot the"`section. A; tra-ck or' guideway 6A vis formed-iny eaclrside edge of the door opening to receive the projections so that the sections j canbe movedvertically in'. the door opening andthey can also be swung about their horizontal' axes. This swinging action, however, is prevented, while the sectionsgare in them'ajor portion of the' door opening by` meansof. the strips 7 placed on of"` eachtrack and receiving thc endv edges of the sections between them, as

shownin' Figure 4t.` Thus' the sections can- ,notbswunlg until they reach the ltoppart ofj tlrefdooropening.- A double track'S is arranged inthe topfof the car for holding th s ect'ions`Y inithetop" of thecar when they are" not inuvs'yej and the doublef'tra'ck'parts are 'connectedfwvith the tra'cks'6` 'by the track vmembers; 9: which are slidably connected Awith tfltpotio'n ofth'ecajr abovefthe door onenin throuffh means ot the bolts enl n e gaging the slots 11.

.Each member 9 has an L-shaped groove 12 therein, the upper part oit which is formed of two branches 1B and la which eX- tead through the edge oi' the member. Vhen each member is in lowered position, the horizontal portion ot the groove will register with a horizontal part 6 of' the track 6, while the branches 13 and 14 will register with the double track 8 so that the sections can be pushed up the liracks 6 throughrthe horizontal parts 6 into the grooves 12 oli' the members 9 and then pass romsaid grooves 12 into either ot the track parts of the double track 8 through the branches 13 and 1st. Byhaving these double tracks in the top of the car, some of the sections can be placed in the upper track parts and others in the lower track parts, as shown in Figure 6, so that all the Sections can be accommodated in the top ot the car. By moving the members 9 upwardly, the grooves 12 therein will be moved out of register with the double tracks Sand the tracks 6 so that the sect-ions can be entirely removed from the car by moving them from the double track parts through the branches 13 of the members 9. then the members 9 ai'e in raised position, extensions 9 thereonl will come opposite the horizontal parts 6 of the tracks 6 and thus close these parts and said members 9 are eld in raised position by spring plungers 15 which will automatically engage the ends 01"' the extensions 9 to hold the members 9 in raised position. liVhenthe members are to be lowered, the plungers must be pushed inwardly by hand. By raising these sections or members 9, they will be out of the way of timber or the like being loaded into the car.

The sections are held in the double tracks by means of the gravity gates or latches 16 which are pivotally arranged in the track parts and normally close these parts under the action of gravity. These members 16 arc so arranged that they will be swung upwardly by the projectionsy on the sections as the sections enter the double track parts, but they will prevent the sections from being lowered again until the members 16 are swung upwardly by hand.

Figure et shows the track 6 as composed et a groove il' Jformed in each side portion of the door opening and a slotted plate 18 covering the groove` the stem ot' each projection 5 engaging' the slot in the plate 18, with the nead ot the projection engaging theV groove 1T. The strips 7 engage the outer portions et the plate 18. rlhe double tracks 8 are formed of channel members whichy have inwardly turned flanges, with a T- shaped partition 8 which divides the channel member into the two track parts. The lower flange and the partition are each masses formed with extensions 8 which engage the position, these extensions forming guide ways for the endsy ot the sections and holding them parallel with the car root. Each member 9 has a part of channel shape to provide the groove 6 for engaging the projections on the sections, as shown in Fig ure 11.

Figure 13 shows a modified form of track in each side of the door opening. In this form, the groove 19 is formed in the corner or the door trame and a roller 2() is fastened to the projection 5 placed on the outer edge ot' a door section, the groove 19 forming a portion ot the track for the roller, the other portion being formed by an oiset part 21 of a strip 22 fastened tothe frame. An eX- tension on the strip 22 forms, with the single strip 7, a guideway for the section to prevent swinging movement ot the same.

Figure lil shows the entire track 23 placed on the outer tace of the door trame.

Figure 15 shows a modication somewhat similar to'that shown in Figure 13, but showing the end ot the section as engaging a gnideway 2/1 formed in each side of the door opening, this guideway being lined by a plate 25.

Figure 16 shows a plate 26 shaped to form the guideway Jfor the ends of the sections and also cooperating with a groove 2T in the outer tace oit the door post for Jforming a track for the roller28 attached to a piojection on a section. In this form oi' the invention, the door sections are arranged outside ot the doorway instead of between the door posts. y

Figure 17 shows a modification somewhat similar to the first form but showing the groove for the head ot" each projection termed by the plates 29 instead ot engaging grooves formed in the door post.

Figure 18 shows the guideways orthe ends of the sections formed by a channel member 30 attached to the inner tace of each door post and a similar channel member 31 attached to the inner tace of the Ydoor post for receiving the projections 82 of the door sections. Y

Figure 19 shows the gnidcways Jfor the ends ot the sections and the tracks for the projections termed by the plates 33 which are attached to the inner faces ot the 'door posts. y

Figure 29 shows a similar arrangement as that shown in F ignre 19, except the plates del. are or" slightly diii'erent shape.

From the foregoing, it 'ill be seen that I have provided simple means for making a grain-tight closnre for a freight car, with means whereby the door sections can be moved to the top ot' the car where they will be out of the way, when not in use, so that the carcan beused' forothe'r purposes than hauling'grain. The sectionsfare heldfagains't swinging movement while' in closing posi-- tion but canV be swungE outwardly 'or inward' ly whenL they are moved tothe upper portion ot'the door opening so that they can be' easily passedinto' the track parts ofY the members?) and passedinto the double tracks at the top of the car. The sections can be entirely removed when necessary by raising the members 9, and said members can be raised so that they will be vout of the way when the car is being used for hauling ma.- terial other than grain.

The drawings also show various ways of forming the tracks and the guideways.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
